反应条件: temp:0.00; pressure:0.00; stir:

反应条件: temp:-78.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of oxalyl chloride (490 μL, 5.6 mmol) in DCM (10 mL) at −78° C. was added DMSO (796 μL, 11.2 mmol) dropwise followed by the addition of a solution of 20b (943 mg, 5.6 mmol) in DCM (2 mL). The mixture was stirred at −78° C. for 30 min and TEA (3.6 mL, 25.5 mmol) was added. The reaction was stirred at −78° C. for 5 min, warmed to rt and stirred at rt for 30 min. The reaction was quenched with water and extracted with DCM. The organic layers were combined and washed with water, dried over magnesium sulfate to give 20c as a yellow semi-solid (880 mg). The reaction was stirred at −78° C. for 5 min warmed to rt stirred at rt for 30 min The reaction was quenched with water extracted with DCM washed with water dried over magnesium sulfate

反应条件: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 20a (29.5 g, 122 mmol) was dissolved in 200 mL of tetrahydrofuran and cooled to 0° C. Lithium aluminum hydride (s) (10.6 g, 279 mmol) was added slowly and the reaction was allowed to warm to rt and stirred for 24 h. The reaction was quenched by slow addition of sodium sulfate hydrated crystals (Na2SO4.10H2O) until there was no bubbling on addition followed by 20 mL of water. The mixture was filtered through Celite®, and the Celite® washed with diethyl ether. The solvent was removed from the filtrate to provide 20 g (97%) of the desired product as a white solid. 1H NMR (400 MHz, CDCl3). to warm to rt The reaction was quenched by slow addition of sodium sulfate hydrated crystals (Na2SO4.10H2O) until there bubbling on addition The mixture was filtered through Celite® the Celite® washed with diethyl ether The solvent was removed from the filtrate
